A wood-fired oven is a special oven that is heated up and cooked by burning wood. Think of it like a big fire pit, but with a special floor and a dome shape on top.
When you put wood into the oven and light it on fire, the flames and heat from the fire go all around the oven and make it really hot inside. This is what cooks the food that is placed inside to be baked, like pizza, bread or even roasted vegetables.
Because the oven is made from special materials, it can keep the heat inside for a long time even after the fire is gone, which makes it really good for cooking food evenly and thoroughly.
A wood-fired oven is a fun and traditional way to cook yummy food!
